6.2 Control Board Faults & Reset (CB300S)
Faults are indicated by a red and green flashing LED located
on the base of the unit in the lower left corner. There is a reset
button on the control board that will reset the unit in the event
of a fault. Pressing the reset button for 3 seconds will reset
the controls and clear the faults. Use the fault list below and
the troubleshooting chart to diagnose the fault and correct any
issues that may be present.
When the LED is glowing solid green, the unit is humidifying and
operating normally. The following list describes the faults that
may occur and will be displayed by the LED’s.
1. Rapid Red Blink = Terminals AP1 & AP2 for the air proving
switch did not close. The unit will not operate until airflow
is present.
2. Slow Red Blink = Once the solenoid valve is energized and
humidification has begun, the controls must see a change
in temperature or the unit will not be allowed to operate.
This may be an indication of interrupted water supply.
3. Alternating Red/Green Blink = One of the thermistors has
failed.
•
If T1 has failed the LED will blink Green/Red/Red with
a two second delay. The unit will not operate in this
condition unless DIP switch #5 is turned ON and the reset
button is pressed.
•
If T2 has failed the LED with blink Green/Green/Red
with a two second delay. The unit will not operate in this
condition unless the T1 thermistor is relocated to act as
T2 and DIP switch #5 is turned ON. Using the override
DIP switch is only recommended as a temporary solution
until the failed thermistor can be replaced.
4. Solid Red LED = This functions to remind the homeowner
to replace the evaporator pad. The unit will continue to
operate and the LED may be cleared by pressing the reset
button on the control board.
